What is Apollo.io?
Apollo.io is a go-to-market platform that combines a B2B contact and company database with AI agents and outreach tools. Apollo says the database holds more than 240 million contacts and 30 million accounts, and you can merge it with your own data and third-party sources.
The platform has three layers. The data layer unifies records and uses waterfall enrichment to fill in missing details. The intelligence layer runs AI agents that research accounts, prioritize leads, draft outreach and book meetings. The execution layer handles email sequences, dialing and deliverability tools, either in Apollo's Workspace or in your CRM, Gmail or browser through Apollo Anywhere and a Chrome extension.
Apollo suits founders, individual sellers and sales teams that do outbound prospecting. It has a free plan with no time limit, and paid tiers add higher credit limits, AI features and team controls.
